What Are QR Codes Used For?

Simply put, QR codes are a medium for storage, like a thumb drive or the solid-state drive (SSD) in your computer. It&#;s printed on a piece of paper or displayed on a screen. Don&#;t get too excited about trying to store much on it, though.

QR code version 40 (the largest size) holds a maximum of KB.

Speaking in purely computer storage terms, KB is tiny. For comparison, the average MP camera on your phone takes a picture that is 3MB in size. That&#;s times larger than the data that can be stored on a QR code.

Instead, QR codes often store letters and numbers in sequence.

Why would you want to store letters and numbers? Let&#;s see a few examples of how they&#;re used and find out why:

• In place of business cards, or on them
• Education aids in classrooms
• Widely used in print advertising
• Fintech, digital wallets, and money transfers
• Product packaging, similar to print advertising
• Travel or other kinds of tickets for authorization and entry
• Event invitations to link to a site, or download information like location

These use cases are by no means the only ways QR codes are utilized. A QR code is used to take digital information from a physical medium into a digital device. Using QR codes as a means for money changing hands has seen the largest use to date, next to advertising.

How Do QR Codes Work?

There&#;s a long and technical version of this answer and a short version.

They work by opening your laptop or phone camera and getting the whole QR code in the frame. If you&#;re on iPhone, the native camera app has it built-in. Android phone manufacturers are starting to catch up on this great idea.

Apps like LINE, WeChat already have this technology built-in. If you want to get someone&#;s contact info they open their app, tap QR code, and you open your app, tap scan and look at your QR code. Now you&#;re friends.

It&#;s as simple as that, without searching for names, email addresses, or phone numbers.

In a day and age where we are a little private about that kind of personal information, especially with OTPs being sent to our personal phone numbers, it&#;s a secure way to connect to new people and network.

The long answer is too long for a beginner&#;s guide like this!
